fluorescence to enhance high-throughput catalyst screening and rapid characterization of catalysts on a small scale. Fluorogenic substrates composed of a fluorophore possessing an amino group are readily prepared as amides of alpha,beta-unsaturated carbonyl compounds and generally exhibit low fluorescence, while Michael or Diels-Alder reactions of these fluorogenic substrates provide products of significantly
我们开发了一种新的光谱系统,用于通过荧光检测碳-碳键的形成,以增强小规模催化剂的高通量筛选和快速表征。由具有氨基的荧光团组成的荧光底物很容易制备为 α、β-不饱和羰基化合物的酰胺,并且通常表现出低荧光,而这些荧光底物的 Michael 或 Diels-Alder 反应提供了显着增强荧光的产物。该产品的荧光比底物高约 20 至 100 倍。该测定系统通过筛选迈克尔反应的潜在催化剂和溶剂优化实验得到验证。具有氨基的荧光团与α、
